*IKt*-algebras were introduced in the paper

*An algebraic axiomatization of the Ewald’s intuitionistic tense logic*by the first and third author. In this paper, our main interest is to investigate the principal and Boolean congruences on

*IKt*-algebras. In order to do this we take into account a topological duality for these algebras obtained in Figallo et al. (Stud Log 105(4):673–701, 2017). Furthermore,...

*IKt*-algebras that we investigate in this paper were introduced in the paper

*An algebraic axiomatization of the Ewald’s intuitionistic tense logic*by the first and third author. Now we characterize by topological methods the subdirectly irreducible

*IKt*-algebras and particularly the simple

*IKt*-algebras. Finally, we consider the particular cases of finite

*IKt*-algebras and complete IKt-algebras.
